Idea Feedback: Dashboard of "metrics that matter" for SaaS startups

I'm thinking of morphing my project into a dashboard of SaaS-specific metrics. It will be like Mixpanel for financial data, showing things like: * Churn * Lifetime Customer Value * Cost per Acquisition * Lifetime Profit per Customer * Customer Acquisition Cost Ratio * Maybe even comparison to the aggregate of other startups? I was inspired by Dave McClure's pirate metrics and essentially want to make Ryan Carson's SaaS spreadsheet http://spreadsheets.google.com/ccc?key=0AkxZrw3662U_dEhQa0Y4T3c5RU5mcGd6N0twYXhLZWc into a trackable, real-time dashboard. I think HN is filled with target customers so I appreciate all the candid feedback.
